I continue on this subject, as i'm still working on that, i have not yet received the camera
So.. Yesterday, i installed the relay.
The wire i found in the trunk for the reverse signal is blue/yellow
I think that's same for all E46.
When i engage reverse, the TV module switches fine to the camera video input.
I did the test by inputing a DVD video source, it works fine.
But, i have one issue, i don't know the reason why, may be someone knows...
I removed the dvd video input from the camera reverse video input, and plug it back to the AV video input. camera reverse video input has nothing now.
1/ If i watch the DVD or TV. when i engage the reverse gear, i can see the DVD / TV picture, but flickering
! (whereas there is no video source in the camera reverse video input)
2/ If i'm in the nav audio menu, when i engage the reverse gear, i can see a black screen (normal i think).
is it normal for the 1st case ?
